It is among the objects of this invention to provide such :an index in which the card sup-1 ports are articulated one to the other and-in whichany support may be removed'trom the others and a new one substituted therefor or in which a Section of'the index may be re- With these and other objects in view which will become more apparent in the following description and disclosures, this invention comprises the novel structure and combinations hereinafter described and moreparticued claims.

In the accompanying .drawings,:A which illustrate certain preferred embodiments of this invention and in whichsimilar reference numerals refer to similarfeatures inthe different views: A T

Figure 4 is an elevational view of themdex involving a slight modification in the manner of attaching the cards to theirsup;

larly pointed out and defined in the append- As shown onth'e drawings: As illustrative of thisinvention, there is shown anindex comprising a series of articulated supports to which cards are attached and from which they are suspended. In Figures l to 3v the cards aredetachablysecured" to the supports while in Figures 4 to, (i the cards'are permanentlyattachedto their supports. Y Each support consists of a flexible strip 1 which is preferably made of thin cardboard or the like. In the lateral edges of each supports-are substantially V-shaped clefts which are respectively spaced a suitable distance from the horizontal edges of the support to provide attaching means or articulating tongues 2 and 3 either of which may be used for articulating purposes. Triangular apex tures 4 are provided near the lateral margins of the supports. I The base of each triangular aperture'lies in a transverse or vertical plane; and the apices aredirected toward the lateral margins or ends of the support and the distance between the outer apices of the apertures corresponds to the distance between the V-shaped clefts to form receiving Ineansfor said clefts. v I v In the present instance, the apertures 4 are offset from the longitudinal center line of each support. As shown, the apertures tare nearer to the-upper edge ofthe support than to the lower edge and thecards are suspended from the upper edge. The exposed margin on each card will substantially correspond to the-distance between the upper edge of the support and the aperture. If the supports are used in invertedpositionthat is, upside down, to support-the cards, this distance becomes greater so that-a larger marginof the cards becomes exposed;

A The manner'of attaching the cards upon these supports will now be described. In Figures 1 to 3, eachsupport has a heavy paper hinge 5 attached thereto. The paper hin'gepreferably has a portion folded over the upper edge of each support and glued or attached to the rear of the support as indieach support is free to swing upwardly into a substantially vertical plane for exposing.

the card therebeneath.

Each paper hinge has a pair of eyelets 8 which are suitably spaced to receive the notches 9 in the lateral edges of the cards 10.- Each eyelet has a disk 11 upon its front end forretaining the cardr The cards 10 integral port-ion l2 folded over the upper edge of each support and, glued or secured to the-back thereof whereby each card is permanently attached toits support. In assembling the index, it is preferable to begin -with the uppermost index card or hinge and-its support and articulate thesec 0nd support with its attached card or hinge ao to the first support; the first card-may readily be swung upwardly for such a purpose. The third support may then be articulatedto the second support and so on. It is hence apparent that index cards may added as needed. If desired the card or sheet supports may be inverted to vary'the exposed margins; In suchcase the cards or sheets will hang suspendedfrom the lower edges of their supports. "Instead of attaching'the cards or.

sheets to the upper margins of thesupports they may be attached to the lower margin. 7

Itwillbe noted that each support overlaps the adjacent support; likewise each nether card-has an expose'd'margin with respect to the overlying card. Further, a sect-ion consisting of a plurality of supports and their cards may readily be removed or replaced as a unit; With'respect to'the structure shown in Figure 1, the cards are also removable from their supports. In the assembled index, it should also be noted that the attached margin Got the card-hingein Figure 3 and the attached portion 12 oft-he card in Figure 6 will be between two'supports 1, which not only obscures the same but also tends to maintain the same-secured. Y r r I am aware that many changes may'be made and numerous details of construction maybe varied through a wide range without departing from the principlesof this invention and I therefore do not purpose limiting "*I claim as my invention: 1

1-. In an index device, a'series of similar edges in offset relation so as to form a series or chain of strips, interlocking means for V detachabl maintaining said strips in chain are placed upon the retaining eyelets or studs by flexing as is well known in the art., Each card may readily be removed from its support by a similar flexing movement. 1

In Figures 4 to 6, each card 10- has an tion of each in visible index relation. 9 3. In an index. device, a series ofisimilar strips superposed on one another with their edges in offset relationso aspto form a series or chain of strips, interlocking means -.for

detachably maintaining said strips in chain form, a series of record cards, and means detachably: and r hingedly: supporting said cards i-noverlapping relation,- one 011 each stripjwith a .free marginal portion of each card in visible index relation.-:

4.'In an index device, a series of similar strips superposed on:one -another with their edgesin ofiset relation so as to form' a series or chain ofstrips, interlocking means for detachably maintaining said strips in chain form; a series of record'cards, and holder members, one holder member being'hingedly connected-to each of said strips, and said members having means for detachably holding :saidirecord cards in overlapping relation-with.a' free marginal portion of each card in visible index relation.

*5. Inan index device, a series of similar strips superposed on one another with their edges in offset relation so as to form aseries or chain-of strips, interlocking means for detachably maintaining said strips in chain form, a series of record cards, a series of card holders,'each card holder having means providing a' hinge connection to one strip, andmeans for detachably connecting each record card to one card holder, said series of cards'having afree marginal portion of each card arranged invisible index relation. 6.1'In an index device, a series of similar strips superposed on one another with their edges in ofi'set relation so as to form a series orchain of strips, interlocking means for detachablymaintaining said strips in chain form,and a series of record cards, each card havinga marginalportion provided with means hingedly .connecting itto a marginal portion of oneof said. strips and supported in said index in -overlapping' relation with a free marginal portion of said card in visible index relation. r

7. In an index device, a strip having interlocking means on opposite marginal portions and cooperating means intermediate said marginal portions unequally spaced from each of said marginal portions, said interlocking means being independently adapted to detachably interlock with the cooperating means on a similar strip to form a series or chain of strips With overlapping edges in visible index relation, one of said inter-' locking means supporting said strips With a Wider visible margin than the other, and a record card on each strip, each record card having a marginal portion secured to its respective strip. a

In testimony whereof I have hereunto subscribed my name.
